Islands In The Mud: The South Texas Banks Provide Crucial Mesophotic Habitat For Coral Communities, Maria Bollinger, Keir J. Macartney, Erin E. Easton, David Hicks

School of Earth, Environmental, & Marine Sciences Faculty Publications

On the continental shelf off the coast of South Texas lie a series of natural hard-bottom structures (rocky outcrops and relic coral-algal reefs) known as the South Texas Banks (STB), which provide critical habitat for benthic organisms and pelagic fish. The depth of the banks, a persistent nepheloid layer, and strong currents have resulted in few studies that provide quantitative biodiversity data on the STB. Using a remotely operated vehicle (ROV), video surveys were conducted to quantitatively describe the mesophotic coral communities and assess habitat suitability of five STB: North Hospital, Hospital, Southern, Big Adam, and Mysterious Banks. Each of …

Unexpected Opportunities For Manatee (Trichechus Manatus Latirostris) Education And Citizen Science, Yvanna M. Strait, Amy Hirons

Marine & Environmental Sciences Faculty Articles

The Florida manatee (Trichechus manatus latirostris) mainly resides within the state's coastal waters, but sharing this habitat with thousands of watercrafts, either registered, unregistered, or visiting, has proven challenging for its survival. The future of manatee research among scientists and citizen scientists has strong potential. By taking advantage of venues of opportunity such as boat shows, not only is local population data gathered, but a stronger positive relationship with the public is forged. When people feel they have a stake in the conservation of a species or habitat, they will likely become and remain engaged.

Stability Of Fishes Assemblage Structure Over A Lustrum In Coastal Wetlands Under Different Disturbances In An Industrial Zone Of The Central Gulf Of Mexico Coast, Carlos E. Cintra-Buenrostro, Alejandro Fierro-Cabo

School of Earth, Environmental, & Marine Sciences Faculty Publications

Shallow coastal wetlands within the territory of an industrial port in southern Tamaulipas, Mexico, were monitored seasonally over a lustrum, focusing on their fishes assemblage and water parameters. The purpose was to characterize these ecosystems that are affected by different disturbances of industrial origin, document changes, and assess potentially degrading terms as the affectations prevailed over the period of study. The wetlands are differentially affected by impacting land uses in their immediate surroundings, by crude oil leaks, and/or by diverse industrial wastewater discharges. Water parameters varied only slightly over time for most sites, and relative disparities among sites remained. The …

Concentration Of Heavy Metals In Three Distinct Algae Families From Humboldt County, California, Kodiak E. Miller, Caleb J. Strait, Jacob I. Begorre, Brittney L. Mitchell, Claire P. Till

IdeaFest: Interdisciplinary Journal of Creative Works and Research from Cal Poly Humboldt

Anthropogenic impacts on marine environments can impact metal fluxes and concentrations available to marine species. Monitoring these impacts is necessary to better understand the interactions between the biotic and abiotic components of these ecosystems and mitigate the risk posed by harmful toxins introduced by human activities. Biomoniters, like macroscopic algae, are useful indicators that illuminate the bioaccumulation of toxins commonly introduced from anthropogenic activity. With this in mind, the concentrations of heavy metals zinc (Zn), nickel (Ni), and copper (Cu) were analyzed via the assessment of algae (Representatives from Ulva, Mastocarpus, Fucus) in two sites in Humboldt County: …

Observations On Late Cretaceous Micrampulla (Corethrales, Bacillariophyceae) From The Campbell Plateau (Zealandia), Southwest Pacific Ocean, Kenta Abe, David M. Harwood, Richard W. Jordan

Department of Earth and Atmospheric Sciences: Faculty Publications

Late Cretaceous (late Campanian) diatom assemblages from the Campbell Plateau (Zealandia), southwest Pacific Ocean, obtained from Deep Sea Drilling Project (DSDP) Leg 29 Site 275, contain well-preserved specimens of two enigmatic diatom species currently assigned to the genus Ktenodiscus; Micrampulla parvula originally described from the Maastrichtian-age Moreno Shale, California, and Pterotheca cretacea from DSDP Site 275. In general, the two species share a number of common features with modern Corethron (domed valves, probable heterovalvate frustules, T-shaped serrated articulated spines, marginal sockets), but differ in the location of the sockets (i.e. vertically at the base of the valve dome and …

Calanoid Copepods Of China Seas, Chang-Tai Shih, Qing-Chao Chen, Yang-Chi Lan, Shih-Hui Hsiao, Chi-Yu Weng

Journal of Marine Science and Technology–Taiwan

Calanoid copepods are a well-recognized taxonomic group of Crustacea. They were already placed, with one cyclopoid (Scribella) and five calanoid (Acartia, Calanus, Candacia, Euchirus (= Euchaeta), and Pontella) genera, under a single taxonomic unit, the Calanidae, by Dana [1]. Giesbrecht and Sars are the two early principal contributors to the taxonomy of Copepoda, including the Calanoida.

Based on the location of the body articulation, Giesbrecht [2] divided copepods into two groups, the Gymnopleoden and Podopleoden. All copepods, characterized by an articulation between the fifth pedigerous (leg-bearing) somite and genital somite, separating the body into an anterior part (prosome) and a …

Spatial Variation In Hard Bottom Coral Communities Of The Coastal West Florida Shelf, Nicole Blank, Sandra D. Brooke, Brian K. Walker

Marine & Environmental Sciences Faculty Articles

Hard bottom coral and sponge communities differ along portions of the West Florida Shelf (WFS) in species occurrence, diversity, and/or size. However, the composition and spatial distribution of these communities are not well understood. Community transitions have been proposed in the central portion of the WFS around Tampa Bay, Cedar Key, and as far south as Charlotte Harbor, but supporting data are sparse. Fifteen sites in three regions of Florida were surveyed for species distribution, density, and demographics. Distinct communities were found between St Teresa, Hudson, and Tarpon Springs. Coral and sponge densities were highest off Tarpon Springs followed by …

Treatments Of Cyanobacteria On Mariculture Sponges In Jambiani, Tanzania, Sally Thornton-White

Independent Study Project (ISP) Collection

Since 2009, Marine Cultures, an NGO, has explored sponge farming in Jambiani to develop secure and sustainable livelihoods for the community. While sponge farming provides economic opportunity for an industry that functions within ecological boundaries, it faces unique issues that threaten its success. As climate change increases global water temperatures, cyanobacteria are causing increased death rates among mariculture sponges. Mitigating these negative effects with sustainable and reliable solutions can help Marine Cultures grow their positive impact. Alternative methods for mitigating cyanobacteria growth were tested during three study phases. Phase 1 tested how sponge health and algae growth responds to being …

Irrigation Decisions In Response To Groundwater Salinity In Kansas, Juhee Lee, Nathan P. Hendricks

School of Earth, Environmental, & Marine Sciences Faculty Publications

Understanding the interaction between groundwater salinity and irrigation decision making has important implications for groundwater management. Econometrics models were estimated using observed farmer behavior in response to different groundwater salinity levels in a region of Kansas. Estimation results demonstrate that farmers in the face of groundwater salinity change their irrigation decisions on irrigated acreage (i.e., extensive margin), crop choice (i.e., indirect intensive margin), and water application depth (i.e., direct intensive margin). The empirical results indicate an overall decrease in water use due to higher salinity, primarily through a decrease at the extensive margin.

Why New Zealand’S Indigenous Reconciliation Process Has Failed To Empower Māori Fishers: Distributional, Procedural, And Recognition-Based Injustices, Hekia Bodwitch, Andrew M. Song, Owen Temby, John Reid, Megan Bailey, Gordon M. Hickey

School of Earth, Environmental, & Marine Sciences Faculty Publications

How is it that the New Zealand government’s process for re-establishing Indigenous fishing rights has failed to deliver thriving Māori fisheries? This paper examines why, at Te Waihora, a coastal lake, and site of one of the nation’s longest running and best-funded state-Māori co-governance agreements, Māori fishers have been unable to use their rights to support their fishery. As of 2018, the lake’s culturally and ecologically significant eel population was no longer commercially viable, a decline fishers have attributed to rampant dairy industry expansion upstream. Drawing on environmental justice literatures, we deploy a multi-dimensional framework to identify factors shaping possibilities …

Evaluating The Potential Effect Of Nitrogen And Toxicological Responses Of Juvenile Lampsilis Reeveiana (Mollusca: Unionidae) In The Buffalo National River, Anna Marie Pieri

Student Theses and Dissertations

The Buffalo National River (BUFF) was established as the first national river in 1972 and later designated as an Extraordinary Resource Water and Natural and Scenic Waterway. This thesis seeks to address the potential threat of elevated nutrients and its association with freshwater mussel declines in the BUFF through laboratory and in situ exposures. Water and sediment chemistry data were collected, and relevant thresholds were used to extrapolate lab-to-field toxicity during low-flow events. Acute toxicity was not observed; however, low-concentration chronic toxicity may be influencing mussel assemblages with rising temperatures. Water quality degradation is likely the result of combined sources …

Purification Of Artepillin C (Arc) With Anticancer Activities From Supercritical Co2-Ethanol Extracts Of Brazilian Green Propolis By Using Adsorption Column Chromatography, Lin-Hsiang Chuang, Wen-Chin Chen, Wen Pei, Ming-Hsi Chuang, Todd Hsu, Po-Chao Chuang

Journal of Marine Science and Technology–Taiwan

Phenolic compounds with varying phenolic structures are present in both terrestrial and marine organisms. Artepillin C (ARC) is a prenylated phenolic compound produced specifically in Brazilian green propolis. Earlier studies have demonstrated the potential of ARC as a dietary supplement for cancer prevention due to its ability to suppress tumor growth and metastasis. Here we report the development of an effective adsorption chromatography combined with supercritical CO2 extraction for the massive purification of ARC. A mixture of supercritical CO2 and ethanol extract of Brazilian green propolis was passed through a stainless chromatographic column packed with protruding metals at 4,000 psi …
